This invention relates to a magnetic skelp charging machine, and has for its object to provide a machine of such class with means, in a manner as hereinafter set forth, whereby pipe slrelp can he quickly charged to a furnace for the purpose of heating the skelp.

A further object ot' the invention is to provide a machine of such class with pairs of continuously operated feed rollers, formed of non-magnetic material. and having arranged therein stationary magnets for attracting the slrelp to engage the periphery of the rollers to up sutiicient friction hetween'the slrelp and the rollers during the feeding of the slcelp so that during the charge of the skelp there will he no slipping thereof, under such circumstances expedi tiously and rapidly feeding the skelp.

A further object of the invention is to provide a machine for the piu'pose set forth includingmeans for supporting the skelp above the feed rollers, during the operation of the latter whereby the skclp can be properly positioned to he charged without the skelp being engaged hjzthe feed rollers until. the operator has shifted the slrelp in position to be charged, and said means capable of being actuated to lower the slrelp to engage the periphery of the feed rollers so that the slrelp will he charged.

A further object of the invention is to provide a means for the purpose set forth, including pairs of feed rollers, the rollers of each pair being formed of non-magnetio material and having arranged thereina stationary magnet for attracting the skelp to engage the periphery of the feed rollers to cause Soilicicnt friction whereby the charge of a slrelp will be continuous, the skelp, during the charging operation being utilized to close the circuit provided by the magnets of each pair of iced rollers.

Further objects oi? the invention are to provide a magnetic slrelp charging means, which is simple in its construction and a1- rangemcnt, strong. durable efficient and convenientin its use, readily set up and com paratigely inexpensive to manufacture.

Vvith the foregoing and other objects in view, the invention consists of the novel construction combination and arrangement of parts as hereinafter more specifically de scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, wherein like reference characters denote corresponding parts throughout the several views: Figure 1 is a top plan view of a magnetic skelp charjng machine in accordance with this inveni ion, Fig. 2 is a side elevation, Fig. 3 is a perspective view of one of the skelp elevating and lowering members, Fig. a is a sectional plan of a pair of feed rollers, Fig. 5 is a vertical sectional View of a pair of feed rollers, and Fig. 6 is a vertical sectional view of a feed roller taken at right angles to the section shown in Fig. 5.

. Referring to the drawings in detail, 7 and 8 denote a pair of rails to provide a track arranged forwardly of a furnace, the latter being illustrated diametrically as at 9. Upon the track rails 7 and 8 is adapted to be shifted the 'magnetic skelp charging machine in accordance with this invention. whereby the slrelp, when charged can be fed to the furnace at different points of the latter.

Mounted upon a truck 10, which travels upon the rails 7 and 8 is the machine frame 11 carryinga constant s eed motor 12, for operating a driving mec ianism 13 for the truck 10. The driving mechanism for the truck 10 may be ofany suitable construction; The controlling lever for the driving mechanism is indicated at 14- The frame 11 is provided with bearings 1 h having journaled therein hn operating shaft 15, which is driven from a constant speed motor-'16. The shaft 15 is op'eratirely connected with the said motor in any suitable manner and said shaft 15 is provided with pairs of beveled gears, the gears of one pair being-"indicated at 16, and the gears of the other pair at 1-7. Two pairs of gears are illustrated, but it is obvious that the number of pairs can be increased depending upon the number of feed rollers employed. The shaft 15 extends longitudinally with respect to the frame 11, and is arranged in.proximity to one sideof said frame 11, the said side being indicated by the reference character 18. The gears 16 are positioned near one end of the shaft 15, and the gears 17 near the other end of the shaft 15:

Connected to the side 18 of the frame 11 and projecting at right angles with respect thereto is a longitudinally disposed table 19 provided with a longitudinally extending angle'shaped member 20, wh1ch projects above the table 19 and constitutes a stop. Projecting from the side 18 of the frame 11 and disposed at right angles with respect thereto is a longitudinally extending plate 21 carrying on its upper face a pair of angle-shaped members 22 and 23, which are disposed longitudinally with respect to the plate 21 and each other and the said mem-- bers 22 and 23 in connection with the plate 21 provide a guide for the skelp as the latter is fed to the furnace. The guide 21 is spaced from the table 19, but arranged in longitudinal alinement with respect thereto. Projecting from the side 18 of the frame 11,at the inner end of said frame is a plate 24 having. arranged on its upper face a pair of longitudinally extending angle-shaped members 25 and 26, which in connection with the plate 24 provide a guide for the skelp as it.

side 18 of the fi nine 11. The stem of the member 27 has 'pivotally connected thereto as at 30 a pair of depenc ing spaced parallel links 31, which have their lower ends pivotally connected as at 32 to a pair of links 33 and to a head 34. The links 33 are pivotally attached to a bracket 35, secured to a plate 36 spaced from the side 18 of the frame 11. The heads 31 are connected together by a longitudinally extending rod 36 and the head 3d of that element which is arranged at the inner end of the table 19 has attached thereto a longitudinally extending rod 37, which is pivotally connected as at 38 to an arm 39 actuated by a lever 40 pivotally attached as at 41 to a bracket 42 carried by the T-bar The members QT'project above the table 19 and plate 21, as clearly illustrated in Fig. 2 and are maintained in such position when the lever 4-0 is in the position illustrated in Fig. 2. If the lever is swung toward the roar cud of the plate 19, the Supporting elements are lowered.

The members 27 are employed to hold a skelp above the feed rollers so that the skelp can be properly positioned prior to the charging of the skelp into the furnace. After the skelp has been properly positioned, the lever 40 is shifted toward the rear end of the plate. 19 lowering the elements 31, so that the skelp will engage the feed rollers and he charged-into the furnace.

As before stated, two pairs of feed rollers are illustrated in connection with the machine, but the number of feed rollers can be increased if desired. The feed rollers of one pair are indicated by the reference char acters -13 and 14 and the feed rollers of the other pair are indicated by the reference characters 45 and 16. The feed rollers 43 and 14 are positioned between the table 19 and plate 21 and the feed rollers 15 and 116 are positioned between the plates 21 and 21. Associated with and fixed to each of the feed rollers is a spindle 47, which is mounted in a .bearing 48 carried by the side 18 of the frame 11 and is provided with a beveled gear 119. The gears 49 mesh with the gears 16 and 17.

Each of the feed rollers consists of a hollow bod portion 50 formed of non-magnetic materia, prefer 'rtbly brass and one end of: the body portion 50 has a hub 51 which is interiorly threaged and engages with the threaded stemfi .of the spindle :17 whereby the body portion 50 is fixed to the spindle 17 so that said jbod portion will rotate with said spindle. 'Tiiecther end of the body portion 50 has SQClncd therein anannnlar member 53 formed with a hub 54.

Arranged in the feed rollers of each pair are magnets 55 and 5G. The pole piece of the magnet 55 is indicated at 57 and the pole piece of the magnet 56 is indicated at 58 and the said pole pieces are permanently out of engagement .with the inner face of the rolls in which their respective magnets are arranged. The magnets 55 and 56 are stationary and each magnet is supported through the medium of a U-shaped member 59, which is. fixedly secured as at (30, to the lower end of a pole piece. One arm of the member 50 is loosely mounted as at (31 upon the stem 52, whereby the said stem will rotate in the arm of the said member 59. The other arm of said member 59 has formed integral therewith a stub shaft 62, which projects through the hub 54 and said shaft provides what may be termed a bearing for the hub 5-1. while the feed roller and spindle rcvolrc. By the foregoing arrangenicnt, it is obvious that the magnets are sus cndcd in a stationary manner within the cod rolls.

The connection between the pole pieces 0 a pair of magnets is had through the medium of an arm 63 of conducting material and the said arm, has secured in its ends, as at 64-, the stub shaft 62 carried by a pair of supporting members 59. The circuit in con nection with a pair of magnets, when feeding the skelp is from the slrelp, through roller =33, pole piece 57, member 59, stub shaft 62, arm 63, other stub shaft 62, through member59, pole piece 58 through roller 44 to skelp. The elevating and lowering device which associates with the rollers is also employed to take the jar and weight of the slrelp oil the rollers until one is ready to charge the slcelp, and after being ready to charge the skelp, the lever is shifted, which lowers the skelp on to the rollers and as the rollers are revolved, the slrclp is charged through the guides into the heating furnace. The magnets in the rollers cause the skelp to be attracted toward the pole pieces which provides traction between the rolls and the skelp and under such conditions there is no slip of the slcelp the same is charged to the furnace. The plate 36 has connected thereto a pickers trough of ordinary construction.
